Some VNC viewers support the TightVNC CursorPosUpdates

and CursorShapeUpdates extensions (cuts down on
|
|
|
|
|
|
|

network traffic by not having to send the cursor image
|

every time the pointer is moved), in which case these

|

|
|
|
|
extensions are used (see -nocursorshape and -nocursorpos
|

below). For other viewers the cursor shape is written
|
|
|
|
|
|
|
|
directly to the framebuffer every time the pointer is
|
|
|
|
|
|
|
|
moved or changed and gets sent along with the other
|
|
|
|
|
|

framebuffer updates. In this case, there will be
|
|
|
|
|
|
|
|
some lag between the vnc viewer pointer and the remote
|
|
|
|
|
|
|
|
cursor position.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
If the X display supports retrieving the cursor shape
|
|
|
|
|
|
|
|
information from the X server, then the default
|
|
|
|
|
|
|
|
is to use that mode. On Solaris this requires
|
|
|
|
|
|
|
|
the SUN_OVL extension and the -overlay option to be
|
|
|
|
|
|
|
|
supplied. (see also the -overlay_nomouse option). (Soon)
|
|
|
|
|
|
|
|
on XFree86/Xorg the XFIXES extension is required.
|
|
|
|
|
|
|
|
Either can be disabled with -nocursor, and also some
|
|
|

|
|
values of the "mode" option below.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The "mode" string can be used to fine-tune the
|
|
|
|
|
|
|
|
displaying of cursor shapes. It can be used the
|
|
|
|
|
|
|
|
following ways:
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
"-cursor X" - when the cursor appears to be on the
|
|
|
|
|
|
|
|
root window, draw the familiar X shape. Some desktops
|
|
|
|
|
|
|
|
such as GNOME cover up the root window completely,
|
|
|
|
|
|
|
|
and so this will not work, try "X1", etc, to try to
|
|
|
|
|
|
|
|
shift the tree depth. On high latency links or slow
|
|
|
|
|
|
|
|
machines there will be a time lag between expected and
|
|
|
|
|
|
|
|
the actual cursor shape.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
"-cursor some" - like "X" but use additional
|
|
|
|
|
|
|
|
heuristics to try to guess if the window should have
|
|
|
|
|
|
|
|
a windowmanager-like resizer cursor or a text input
|
|
|
|
|
|
|
|
I-beam cursor. This is a complete hack, but may be
|
|
|
|
|
|
|
|
useful in some situations because it provides a little
|
|
|
|
|
|
|
|
more feedback about the cursor shape.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
"-cursor most" - try to show as many cursors as
|
|
|
|
|
|
|
|
possible. Often this will only be the same as "some".
|
|
|
|

x11vnc -rfbauth $HOME/.vnc/passwd -nap -flashcmap -cursorpos -norepeat
|
|
|
|
x11vnc -rfbauth $HOME/.vnc/passwd -nap -flashcmap -cursor X -norepeat -add_keys
